首先需要引入dwr
jar包到工程中的lib中
在web
xml中配置dwr
如下
<!
DWR配置
>
<servlet>
<servlet
name>dwr
invoker</servlet
name>
<servlet
class>org
directwebremoting
servlet
DwrServlet</servlet
class>
<init
param>
<param
name>scriptCompressed</param
name>
<param
value>false</param
value>
</init
param>
</servlet>
<servlet
mapping>
<servlet
name>dwr
invoker</servlet
name>
<url
pattern>/dwr/*</url
pattern>
</servlet
mapping>
然後在WEB
INF下創建一個dwr
xml
並在裡面將調用處理類配置
例如
<dwr>
<allow>
<convert match=
com
po
OneSearchDto
converter=
bean
>
<param name=
include
value=
resname
resid
>
</param>
</convert>
<create javascript=
GetDataBaseRes
creator=
new
>
<param name=
class
value=
com
util
GetDataBaseRes
>
</param> <include method=
getDataBaseRes
/>
</create>
</allow>
</dwr>
然後在需要調用的jsp中
將調用處理js類引入
如下
<% String contextPath = request
getContextPath()
%>
<script type=
text/javascript
src=
<%=contextPath %>/dwr/interface/GetDataBaseRes
js
>
</script>
<script type=
text/javascript
src=
<%=contextPath %>/dwr/engine
js
>
</script>
<script type=
text/javascript
src=
<%=contextPath %>/dwr/util
js
>
</script>
調用的js例子如下
function query()
{
var keyWord = document
getElementById(
keyWord
)
value;
var dataStr =
;
var arr = document
getElementsByName(
checkboxData
)
for(var i=
;i<arr
length;i++)
{ if(arr[i]
checked)
{ dataStr+=
+arr[i]
value;}
GetDataBaseRes
getDataBaseRes(keyWord
dataStr
disPoseRes)
}
function disPoseRes(str{ alert(str)
}
如果需要在dwr調用類中獲得session
或者request
如下
org
directwebremoting
WebContext wc = org
directwebremoting
WebContextFactory
get()
HttpSession session = wc
getSession()
HttpServletRequest request = wc
getHttpServletRequest()
